Be it known that I, WALTER KENNEDY, a citizen of the United States, residing at Alle: gheny, in the county of Allegheny and State of Pennsylvania, have invented or discovered certain new and useful Improvements in Plants for the Manufacture of Coke, of which improvements the following is a specification.

The invention described herein relates to certain improvements in plants for the manufacture of coke, and has for its object a construction and combination of elements whereby the coke can be easily removed from the coking-hearth and charged into a car, in which it can be quenched or transferred to a quenching or storage bin.

It is a further object of the invention to provide for the utilization of the products generated during the burning of the coal.

The invention is hereinafter more fully described and claimed.

In the accompanying drawings, forming a part of this specification, Figure 1 is a view,

Figs. 5 and 6 are sectional elevations on planes indicated by the lines V V and VI VI, Fig.4. Figs. 7 and 8 are detail views showing the detachable connection between the oven and gas-main. Fig. 9 is a sectional detail view on a plane indicated by the line VIII VIII, Fig. 4; and Fig. 10 is a top plan view of the buggies or trolleys employed for hoisting and shifting the ovens, 85o.

In the practice of my invention two lines of hearths 1 and 1'- are formed on opposite sides of a line of rails 2 and in such relation thereto as to permit the passage of a carA between the hearths and with the bottom of the car on a level with the upper surface of the hearths. Under each of the hearths are formed a series of fines 3, which connect at their outer ends to combustion-chambers 4 4, intowhich gas maybe introduced, as hereinafter described. At their innerends these lines connect with sewers or flues 5 and 5, which in turn connect with a suitable (Not shown.) The car or cars are Fig. 2 is a top plan provided on their sides with hinged plates 6, which when turned up will form retaining sides for the car, but when turned down form continuations or prolongations of the carbottom and extend to the edges of the hearths, so that the floors of the cars and the upper surfaces of the hearths, which are on a common level, or approximately so, are connected by bridges formed by the plates 6. On these hearths are arranged a series of two or more ovens 7 7, consisting of an arch framework formed within metal shells 8, so as to permit of the handling of these ovens, as will be hereinafter described. The tops of the ovens are provided with openings 9, through which fresh fuel may be charged thereinto; but these openings are normally closed by stoppers 10 while coking is being effected. Flues 11, formed in the walls of the oven, are connected at their inner ends with the oven, while their outer ends are adapted to be connected to gas-mains 12 12. The connections between the gas-mains and the fiues 11 are formed by pipes 13 13, having their outer ends connected to sliding plates 14 14, which are held in contact with plates 15 15, formed on the outer ends of nozzles 16 16, projecting from the conduits or pipes 12 12, by means of weighted levers 17 17, pivoted to the pipes 12 l2 and having rollers 18 so mounted thereon as to bear upon the upper surfaces of the plates 15 15. The outer ends of these levers are weighted, so that with the rollers 18 forming the fulcra they will hold the plates 14 closely in contactvwith the plates 15. The plates 14 and pipes 13 are shifted along the plates 15 by means of pinions on the shafts of hand-wheels 19 engaging racks formed on the plates 14, the shafts of said hand-wheels being mounted in bearings secured to the plate 15. By this construction the pipes 13 13 can be moved toward and from the fiues 11 11 as required. Openings are formed through the plates 14, which will register with the nozzles 16 when the inner ends of the pipes 13 (said ends having supports 13") have been adjusted or shifted into the ends of the Ilues. When the pipes are shifted away from the fines, blank portions of the plate 14 will cover the nozzles 16 and prevent any escape of gas from the conduit. The gases generated within the ovens may be conducted by the conduits 12 12 to any suitable point, where they may be washed or otherwise treated to save the by-products, or the gas may be utilized for heating purposes. When the gas is used for heating the hearths,

the conduits 12 are provided with a series of provided with a series of branches 24, having their lower ends connected to the boxes 21. Where both conduits 12 and 23 are connected to the boxes 21, a valve 25 is employed for the purpose of connecting the one or the other of the branches 20an'd 24 with the boxes. This construction permits of the use of the gas either before or after the elimination of the by-products.

After the charge of coal'h'as been coked in an oven the latter is slid along the hearth and across the bridge 6 and onto the car, carrying with it the charge of coke, which is still in a highly-heated condition. The oven is then raised, leaving the charge on the car, and

returned to the hearth. A desirable mechanism for this purpose consists of an overhead crane. This crane consists of a bridge 25, provided with rollers at its ends adapted 'to'move along rails 26, which are supported *bya suitable framework extending along the entire line of ovens. On the bridge is mounted a buggy 27, having wheels 28, adapted to move along rails on the bridge.

motor-known in the art--as, for example, by an'electric motor 51, having its arms or shaft "connected by suitable gearing to oneo'r'bo'th of the axles of the Wheels 28 of the buggy. 'Four rods 29 extend down from the'bu'ggy on each side of the bridge and have their lower "ends connected to cross-bars 30, provided with hooks 31, adapted to engage pins 32, secured to the sides of the ovens. These rods 29 are preferably braced by rods 33 and are held in position laterally by means of friction-rollers '34, carried by the rods and bearing against guide-frames 35, depending from the'buggy. Any'suitable means may be employed 'for raising and lowering the rods and with them the ovens-such, for example, as nuts 36,fitting' over the threaded upper ends of the "rods. The peripheries of these nuts, which rest upon suitable ab'utments 37 on 'the buggy,'are provided with teeth suitably constructed to engage worms on the outer ends of shafts 38,

having pinions 39 keyed to the innerends. These pinions i'ntermesh with pinions 52 on shafts driven by any suitable motor 53, so as to raiseor lower the rods and the ovens'hung thereon. When it is desired to shift an oven In lieu.-

This buggy is adapted to be shifted by any suitable form of from the hearth onto the car, the buggy is moved along to a suitable position over the oven and the rods lowered, so that the hooks 31 may engage the pins 32 bya lateral movement. to shift the oven out of contact with the hearth. The buggy is then shifted along the bridge by its motor, thereby carrying with'it the oven and sliding the charge contained therein over the hearth onto the car. The oven is next raised and moved back again to position onto the hearth, where a new charge of coal is placed therein, and its fine 11 connected to the gas-conduit 12. The coke may be quenched as soon as the oven is removed or may be carried along in the car toasuitable point, where it maybe dumped into a tank containing Water and-thence removed by any suit-able means to cars ora point of storage. It is preferable, however, to effect the quenching of the coke while in the car by means of steam, and to this end a cover '40 is provided for the car. As soon as the coke is placed in the car the side or sides 6 thereof are turned up, the oven removed, and the cover 40 placed over the car. Steam is next forced into the car through'the nozzles projecting from the pipes 41 through the sides of the car. This pipe is connected tea-feedpipe 42, secured to the car'and adapted to be connected bya coupling to a suitable steamsupply, as the boiler of a locomotive. An auxiliary trolley 43 is mounted upo'n'rails-secured to the bridge 25 for the purpose of handling the cover of the car. This buggy or trolley is provided with a suitable shiftingmotor 54 and lifting-motor 55. The bottom of the car is preferably formed of pivoted sections to permit of the ready removal of the coke therefrom. I

At one end of the line of ovensan elevated track 44 may be arranged for coal-'cars, so that the coal may be discharged down a suitable chute into a bucket4'5, suspended from a buggy 46, mounted on an auxiliary bridge 47 on the rails 26. The bucket 45 is formed with a'discharge-opening in its bottom,- so that the coal may be discharged easily into the ovens.

For the purpose of storing the coke and charging into cars elevated bins48 are arranged at one end of the line of ovens. The coke is discharged from the car A into the chute 49, from which it passes into the hoisting-ears 50, arranged on rails passing up over the bins 48. The cars 50 and rails are constructed to effect an automatic dumping of the'ch'arge into the bins.
